Radeon HD 4350 vs Radeon R9 M290X

Intro

Compare those specifications to the Radeon R9 M290X, which has GPU core speed of 850 MHz, and 4096 MB of GDDR5 RAM running at 1200 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.

Memory Bandwidth

Performance-wise, the Radeon R9 M290X should in theory be much superior to the Radeon HD 4350 in general. (explain)

Radeon R9 M290X		153600 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 145600 (1820%)

Texel Rate

The Radeon R9 M290X will be quite a bit (approximately 1378%) more effective at AF than the Radeon HD 4350. (explain)

Radeon R9 M290X		68000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 63400 (1378%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M290X is a better choice, and very much so. (explain)

Radeon R9 M290X		27200 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 24900 (1083%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
